The atria refer to which part of the heart?

Lower chambers
Upper chambers
Heart valves
Heart muscles

The correct answer is: Upper chambers

The atria are the upper chambers of the heart, which receive blood from either the body (right atrium) or the lungs (left atrium) and pump it into the ventricles (lower chambers). Option A is incorrect because it refers to the ventricles as the lower chambers, while option D incorrectly identifies the atria as heart muscles. Option C is also incorrect because while the heart valves play a crucial role in the function of the heart, they are not part of the atria.
